unifdef
UNIFDEF(1) General Commands Manual UNIFDEF(1)NAME
unifdef - remove ifdef'ed lines
SYNOPSIS
unifdef [ -t -l -c -Dsym -Usym -idsym -iusym ] ... [ file ]
DESCRIPTION
Unifdef is useful for removing ifdef'ed lines from a file while otherwise leaving the file alone. Unifdef is like a stripped-down C pre-
processor: it is smart enough to deal with the nested ifdefs, comments, single and double quotes of C syntax so that it can do its job, but
it doesn't do any including or interpretation of macros. Neither does it strip out comments, though it recognizes and ignores them. You
specify which symbols you want defined -Dsym or undefined -Usym and the lines inside those ifdefs will be copied to the output or removed
as appropriate. The ifdef, ifndef, else, and endif lines associated with sym will also be removed. Ifdefs involving symbols you don't
specify are untouched and copied out along with their associated ifdef, else, and endif lines. If an ifdef X occurs nested inside another
ifdef X, then the inside ifdef is treated as if it were an unrecognized symbol. If the same symbol appears in more than one argument, only
the first occurrence is significant.
The -l option causes unifdef to replace removed lines with blank lines instead of deleting them.
If you use ifdefs to delimit non-C lines, such as comments or code which is under construction, then you must tell unifdef which symbols
are used for that purpose so that it won't try to parse for quotes and comments in those ifdef'ed lines. You specify that you want the
lines inside certain ifdefs to be ignored but copied out with -idsym and -iusym similar to -Dsym and -Usym above.
If you want to use unifdef for plain text (not C code), use the -t option. This makes unifdef refrain from attempting to recognize com-
ments and single and double quotes.
Unifdef copies its output to stdout and will take its input from stdin if no file argument is given. If the -c argument is specified, then
the operation of unifdef is complemented, i.e. the lines that would have been removed or blanked are retained and vice versa.
SEE ALSO diff(1)DIAGNOSTICS
Premature EOF, inappropriate else or endif.
Exit status is 0 if output is exact copy of input, 1 if not, 2 if trouble.
BUGS
Does not know how to deal with cpp consructs such as
#if defined(X) || defined(Y)
